Product details

Regarding the role played by the incorporation of water-reducing agents in concrete,

A. If the mixing water consumption is not reduced, the fluidity of the mix can be significantly improved

B. When water is reduced without reducing cement, the strength of concrete can be increased

C. If the water reduction is accompanied by an appropriate reduction in the amount of cement, the cement can be saved.

Commonly used concrete admixtures (admixtures mixed with chlorine salts should pay special attention to the corrosion of steel bars and concrete; Steam curing concrete and prestressed concrete, do not mix air entrainment agent and air entrainment water reducing agent)

(1) Water-reducing agent (with water-reducing enhancement)

The technical and economic effect of adding water reducing agent: improve strength, improve compactness, improve durability, improve fluidity, save cement Main varieties: ordinary water reducing agent lignosulfonates, such as lignosulfonates (wood calcium powder, M type); High efficiency water reducing agent, such as NNO (concrete mixed with NNO, durability, sulfate resistance, impermeability, steel corrosion resistance is better than ordinary concrete)

(2) early strength agent (can improve the early strength, and has no significant effect on the later strength)

Application: The main types of concrete used in emergency repair projects and motor construction: chloride, sulfate, triethanolamine (3) air entrainment agent (reduce the bleeding segregation of the mix, improve workability, improve the frost and thaw durability of hardened concrete)

Air entraining and water reducing agent has obvious water reducing effect and large water reducing rate, which not only plays the role of air entraining, but also improves the strength of concrete and saves the amount of cement. Air entraining agent and air entraining and water reducing agent are suitable for steam curing concrete and prestressed concrete in addition to antifreeze, impermeable and sulfate resistant concrete. The effect of rosin hot polymers is better, and the most common use of (4) retardants (delay the concrete setting time, and do not significantly reduce the late strength of concrete)

Application: Large volume concrete, concrete under hot climate conditions, concrete for long distance transportation Main varieties: sugar (calcium sugar), Lignosulfonates (calcium Lignosulfonate)

(5) pumping agent (can improve the pumping performance of concrete mix, concrete can smoothly pass through the pipeline, no blocking, no segregation, good viscoplastic).
